GLUING OR PASTING MACHINE.

SPECIFICATION forming part of Letters Patent N o. 685,566, dated October 29, 1901.

Application filed Tune 1'7, 1901.

To a/ZZ whom it may concern:

Be it known that I, FREDERICK WILLIAM BROWN, a citizen of the United States, and a resident of Berlin, in the county of Coos and State of New Hampshire, have invented certain new and useful Improvements ingGluing or Pasting Machines, of which the following is a full, clear, and exact description. Y

The object of the invention is to provide a new and improved gluing and pasting machine, more especially designed for securing a burlap lining on a sheet of wrapping-paper and coating the latter with an adhesive substance to secure the article formed upon the ends and edges of the paper rolls, especially large paper rolls, such as newspaper rolls, to protect the edges of the rolls from damage during transportation, loading, and other handling of the rolls.

The invention consists of novel features and parts and combination of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of `the invention is represented in the accompanying drawings, formingv a part of this specification, in which similar characters of reference indicate corresponding parts in allthe views.

Figure lis a side elevation of the improvement with parts brokenout. Fig. 2 is a front end elevation of the same. Fig. 3 is an enlarged sectional elevation of the front end of the machine. Fig. t is a side elevation of a modified form of the improvement. Fig. 5 is a sectional side elevation of a modified form of the paste-reservoir and the outlet-valve for the same, and Fig. 6 is a perspective view of the rear side of the paste-reservoir shown inFig.3. v

The improved machine illustratedin Figs. 1, 2, 3, and 6 is mounted ona suitably-constructed frame A, in which are journaled a roll of paper B and a roll of burlap C. The paper B after unwinding from the roll passes over a coating-'roller D for coating one face of the paper with glue or other adhesive substance supplied to the coating-roller D by a fountain-roller E, mounted to turn in a fountain F, having awater-heater F at the bottom and receiving its supply of glue or other adhesive substance through a pipe G from a glue-reservoir H, supported on the frame A Serial No. 64,923. (No model.)

' above the fountain F, which latteris also supported on the said frame A. The pipe G is provided with a valve G for filling the fountain F from the reservoir H whenever necessary, and the said reservoir H is provided with a water or steam heater I for keeping the adhesive substance in proper condition. 'Ihe burlap C passes with the coated sheet of paper B between the rollers J and K, mounted to rotate in suitable bearings on the frame A, the roller J acting as a pressingroller and the roller K as a drying-roller. The roller J is preferably made solid and journaled in boxes J, slidable vertically in brackets J 2, carried by the frame A, the said boxes resting on springs J 3 and the tops of the boxes being engaged by set-screws J4 for adjusting the boxes and the roller J according to the desired pressure to be given to the burlap` and the paper. The roller K is made hollow and lled with steam or hot water, so that when the superimposed paper B and the burlap C pass between the two rollers J and K the burlap is glued to the under coated side of the sheet B. In order to place an adhesive substance on the top or outer face of the paper B,the paper,with theburlap secured to the under side thereof, is passed under a roller L receiving paste or other adhesive substance from one or more spouts N of a paste-reservoir N, supported on the frame A. In the spouts N are pivoted valves N2, (see Fig. 3,) carrying on the outerends ofthe pivots crankarms N3, (seeFig. 6,) connected by links N4 with levers N5, fulcrumed on the frame A. In the forward ends of the levers N5 is journaled the roller L, and the rear ends of the levers carry weights N6, the aggregate weight of which is slightly less than the weight of the roller L. lThe united burlap and paper yextend from the under side of the 'roller L over a support O, secured on the front end of the frame A, and the top surface of this support is in horizontal alinement with the top of the drying-roller K, so that when the united burlap and paper extend loosely from the roller K to the support O the roller L presses the united` burlap and paper downward, as shown in Fig. 3, and when 'the operator exerts a pull on the united burlap and paper in a forward direction the burlapA and paper are stretched between the drying-roller IOO K and the support O, and consequently the roller L is lifted upward, and an upward swinging motion is given to the levers N5, which by the links NL and the crank-arms N3 causes the valves N2 to open, so that paste iioWs through the spouts N upon the peripheral surface of the roller L. As the united paper and burlap is pulled forward by the operator the roller L is rotated, thus coating the top or outer face of the paper with the paste or other adhesive substance.

Over the front edge of the support O operates a knife P for cutting off a desired length of united paper and burlap, and the knife P is secured on a transversely-extending bar P', fulcrumed at P2 on the main frame A, (see Fig. 2,) and the :front end of thc bar P is connected by a rod Q with a treadle Q' under the control of the operator. A spring Q2 presses the rod Q, so as to normally hold the bar P and the knife P in an uppermost position; but when the operator presses the treadle Q a downward swinging motion is given to the knife P to cutoff the united burlap and paper at the edge of the support O. The operator then takes this burlap-lined wrapping-paper and presses one end, either burlap side or paper side, aga-inst the front gluing-roll R and then coats it with glue, which makes the ends more adhesive when applied to the edge of news or other kind of paper rolls. It is understood that the piece cut offis provided on the paper side with paste, which is supplied by the roller L, 'so that this piece may be readily used as a covering for a paper roll and by the adhesive substance can be secured to the paper roll for protecting the edges thereof, it being expressly understood that the paste and glue on the paper serves to cause the piece to adhere to the paper roll. Vhen the operator releases the treadle Q and the spring Q2 returns the knife P to an uppermost position, then the united paper and burlap extending between the support O and the drying-roller K is relieved of pressure, and consequently the rollerL now moves downward to the position shown in Fig. 3, and in doing so the valve N2 is again closed. On the next pull by the operator on the burlap the roller L is again lifted and rotated and paste is supplied to the peripheral surface thereof, as previously explained. Thus the valve N2 is opened only during the time that the united paper and burlap is pulled forward to supply the roller L with paste for coating the top or outer face of the paper. The end of the cut-olf piece of united burlap and paper can be supplied with glue, and for this purpose the operator rubs the end on the peripheral surface of a roller R, extending into a trough containing glue, the said roller R being driven from the drying-roller K by a suitable sprocket-wheel and sprocket-chain gear S, as illustrated in the drawings. The reservoir N (shown in Fig. is formed with a spout N8, in which is seated a valve N, carrying at its lower end a friction-roller N10 in contact with the peripheral surfaceof the lroller L, so that when the latter is lifted, as previously described, the valve N is lifted off of its seat to allow the adhesive substance to flow from the reservoir N upon the peripheral surface of the coating-roller L to coat the paper, as previously explained. WVhen the roller L moves downward on releasing the united paper and burlap, the valve N9 by its own weight and the pressure of the adhesive substance in the reservoir N immediately moves to its seat to stop further outfiow of the adhesive substance for the time being.

In the modified form shown in Fig. 4c a single reservoir T is employed,having two valved outlet-pipes T and T2, of which the pipe T supplies adhesive substance to a fountain F2, containing the coating-roller B for coating one face of the paper B as the latter passes from the guide-roller U to the guide-roller U' previous to receiving the burlap C. The paper and burlap pass together between the rollers K' and J5, of which the roller J5 is a drying and pressing roller, is journaled similarly to the roller J, previously described, and is filled with steam or water, the saine as the roller K above referred to. The other pipe T2 serves to supply adhesivo substance to a fountain N7, containing a fountain-roller Vin contact with the coating-roller L for supplying the adhesive substance to the under side of the burlap after uniting the cutoff article to the paper roll, as previously explained, the piece being cut off by the knife P actuated by the operator working the treadle Q, as before explained. A sieve N11 is preferably arranged in the reservoir N to prevent lumpy matter in the paste from passing to the roll.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patenty 1. A machine of the class described provided with a pair of uniting and drying rollers, a support spaced from the said rollers and over which the united fabric passes, and a coating-roller mounted between the support and the uniting and drying rollers for apply ing an adhesive substance to one surface of the united fabric, as set forth.
